If the printer is not able to connect to the network through auto-negotiation, set the link setting by one of the
following methods:
●
The front panel.
●
The Embedded Web Server.
●
Telnet interface, through a system command prompt.
●
A TFTP (Trivial File Transfer Protocol) configuration file that is downloaded, for example, from a BootP
or DHCP server.
●
Network management tools such as HP Web Jetadmin.
Reset network parameters
Network parameters (for example, the IP address) can be reset to factory default values: Front Panel >
settings > connectivity > network connectivity > advanced > restore factory settings and then turning the
printer off and on again. After restoring, print an Connectivity Configuration page to confirm that factory
reset values have been assigned.
CAUTION: A factory-installed HP Jetdirect X.509 certificate will be saved over a cold reset to factory default
values. However, a Certificate Authority (CA) certificate that has been installed by the user to validate a
network authentication server will not be saved.
